Hi everyone, I need some help indentifying the maker and year of a particular piece I picked up in an auction. On the side there is a small symbol - 8 arrows . On the bottom I see a symbol of a sun followed by the letters 'M' 'B' and the letters MAP PIN. Below that there is a serial number 'S4666' and the word IMPERIAL. Is anyone able to tell me anything about this? All help is appreciated, cheers
